Description

Technical Field

[0001] This utility model relates to the field of heat exchanger manufacturing technology, specifically to a heat exchanger fin mold that is easy to demold. Background Technology

[0002] Corrugated fins have an undulating, wave-like shape and can be pressed into specific waveforms, such as herringbone, from flat fins. This wave-like structure causes the flow direction of the fluid to constantly change as it flows through the fins, creating turbulence. This flow change can powerfully propel the fluid, separate and disrupt the boundary layer, thereby enhancing heat transfer, and is commonly used inside heat exchangers.

[0003] A search revealed a patent document with publication number CN217252206U, which discloses a refrigerator air-cooling fin mold. This utility model provides a refrigerator air-cooling fin mold, relating to the field of fin mold technology. It includes a fin mold with buffer support plates installed on both sides of its bottom, buffer pads installed at both ends of its bottom, a bottom support plate fixedly installed on the bottom of the buffer support plates, and a sliding groove fixedly installed on the bottom of the bottom support plate. This utility model, by providing buffer support plates connected to the bottom of the fin mold via mounting strips, and further supported by buffer pads connected to the mounting plate, facilitates effective buffering during the stamping process through the overall cooperation of the buffer support plates and buffer pads. This helps reduce the problem of errors caused by gaps in the top mold components due to long-term stamping caused by large impact forces during stamping, ultimately resulting in defective and unusable fins.

[0004] During use, the above technical solution is prone to failure accidents such as material jamming and mold breakage due to uncontrolled fin demolding.

[0005] Therefore, it is necessary to invent a heat exchanger fin mold that is easy to demold to solve the above problems. Utility Model Content

[0011] Preferably, several sets of sliding rods are fixedly connected to the bottom ends of both sides of the impact seat. The sliding rods are slidably connected to the inside of the stamping seat.

[0012] Preferably, a limiting plate is slidably connected to the outer wall of the sliding rod, the limiting plate is fixedly connected to the surface of the stamping seat, and both ends of the stamping seat are fixedly connected with height-increasing pads.

The water collecting tank 202 pressurizes and sprays the liquid inside the fixing base 201. A flow divider 204 is installed at the top of the pressure pump 203, through which the liquid is pumped... Liquid is diverted and guided. A lower mold 206 is installed at the top of the diversion seat 204 and is mounted on the surface of the stamping seat 1. The surface of the lower mold 206 has impact holes 207 that communicate with the diversion seat 204. Through the cooperation of the pressurizing pump 203 and the diversion seat 204, high-pressure liquid is pushed up by the impact holes 207, making it easy to demold. The surface of the stamping seat 1 has two sets of filter holes 209. Two sets of transfer pipes 205 are fixedly connected to the bottom of the stamping seat 1. The transfer pipes 205 are connected to the collector. A water tank 202 is fixedly connected. The surrounding squeezed water is collected through a filter hole 209 and then returned to the interior of the fixed base 201 via a transfer pipe 205. An upper mold 208 is positioned above the impact hole 207, and the upper mold 208 and impact hole 207 are staggered. An impact seat 5 is fixedly connected to the top of the upper mold 208. The upper mold 208 and lower mold 206 are closed by the stamping action of the impact seat 5, thereby producing corrugated fins. A top seat 6 is fixedly connected to the top of the stamping base 1, and a drive mechanism 7 is installed on the top of the top seat 6. The output end of the drive mechanism 7 is connected to the stamping base 1. The top of the impact seat 5 is fixedly connected. The drive mechanism 7 is started to drive the impact seat 5 to perform stamping. Through the cooperation of the stamping seat 1 and the demolding mechanism 2, after the upper mold 208 is driven downward by the impact seat 5 to close with the impact hole 207 and reset, the pressure pump 203 is started to make the liquid inside be pressurized and then diverted by the diverting seat 204. Finally, the high-pressure liquid gushing out through the impact hole 207 pushes out the fins stamped on the surface of the lower mold 206, thus achieving demolding. The liquid is recovered and filtered by the cooperation of the filter hole 209 and the transfer pipe 205, thereby achieving reuse.

[0026] Refer to the instruction manual appendix Figure 1-5Several sets of sliding rods 8 are fixedly connected to the bottom ends of both sides of the impact seat 5. The sliding rods 8 are slidably connected to the inside of the stamping seat 1. A buffer pad 4 is provided below the sliding rod 8 and is fixedly connected to the surface of the fixed seat 201. The sliding rods 8 and the impact seat 5 cooperate to guide and limit the impact seat 5. A limit plate 3 is slidably connected to the outer wall of the sliding rod 8. The limit plate 3 is fixedly connected to the surface of the stamping seat 1. A raising pad 9 is fixedly connected to both ends of the stamping seat 1. The raising pad 9 is at the same height as the lower mold 206. The punch pad 4 buffers the punching of the impact seat 5, and limits the movement and height of the fin material through the cooperation of the limiting plate 3 and the raising pad 9. Through the cooperation of the limiting plate 3, the buffer pad 4 and other parts, the sliding rod 8 and the impact seat 5 are used to guide and limit the movement path of the impact seat 5 to improve accuracy. The cooperation of the buffer pad 4 and the impact seat 5 buffers the punching pressure, reducing the probability of gaps in the upper die 208 due to long-term punching. The cooperation of the limiting plate 3 and the raising pad 9 limits the movement and height of the fin material.

[0027] The working principle of this practical application is as follows:

[0028] Refer to the instruction manual appendix Figure 1-5 During the production of heat exchanger fins, the fin material is pushed to the working position along the riser pad 9 and the limiting plate 3. Then, the drive mechanism 7 is activated to drive the impact seat 5 to perform stamping, so that the upper mold 208 and the lower mold 206 are closed. During the stamping process of the impact seat 5, the sliding rod 8 is used to guide and limit the movement path of the impact seat 5 to improve accuracy. The buffer pad 4 is used to buffer the stamping pressure through the cooperation of the impact seat 5, reducing the probability of gaps in the upper mold 208 due to long-term stamping. Then, the impact seat 5 is reset under the control of the drive mechanism 7, and the pressurization pump 203 is activated so that the liquid inside is pressurized and diverted by the diverter seat 204. Finally, the high-pressure liquid gushes out through the impact hole 207 to push out the fins stamped on the surface of the lower mold 206, thus achieving demolding. The liquid is recovered and filtered by the cooperation of the filter hole 209 and the transfer pipe 205, thereby achieving reuse.
